AMD R R-260H 

Released May, 2012
  • 2.1 GHz
  • Dual core

How did the Radeon 255 managed to fit in the R9 brand when its performance would be far more lower than that of the R7 260?

The GPU features 896 Stream processors, 56 TMUs and 16 ROPs while the core clock is maintained at 1.1 GHz and 6.50 GHz effective clock for the memory.

The two cards which AMD plans to release are nowhere in line with the top dogs of the R9 series and the R9 260′s specifications completely match those of R7 260X hence causing some confusion among the buyers.
It looks like AMD is going to launch two new products in their Radeon lineup which include the Radeon R9 260 and Radeon R9 255 aimed towards the sub-$150 market.
Dual graphics with the Radeon R7 series will help leverage the GPU performance of these processors bringing great performance to cheaper PC setups.
Clocks are maintained at 1.0 GHz for the core while the memory operates at 6.0 GHz effective clock speed aside a 128-bit memory interface.
